Halloween originated from a pagan festival called “Samhain” meaning “end of summer." The Celts believed that on the eve of Halloween dead spirits would visit the mortal world. They lit bonfires to keep evil spirits away and dressed in disguises.

Although modern-day Halloween is less about dead spirits and more about having fun and dressing up, there are some traditional aspects of an Irish Halloween that we have kept going. 

Here’s a look at some of the ancient and more recent Halloween traditions from Ireland that have stuck over the years!

The bonfire 

Samhain was seen as the end of summer but also the beginning of another year. It was also the one day of the year when spirits could walk the earth. The community would gather together and light huge fires to ward off bad fortune for the coming year and any evil spirits.

Some believe that people extinguished their fires in the hearth at home before they left and would reignite them using an ember from the bonfire, for good luck. The day after the bonfire the ashes were spread across the fields to further ward off bad luck for the farmers during the year.
It was also traditionally believed that the bonfire encourages dreams, especially of your future husband or wife. It was said that if you drop a cutting of your hair into the embers of the fire the identity of your first husband would be revealed.


There are two schools of thought on why the Irish carried Jack-o-lanterns. One is that it is an ancient Celtic tradition. In order to carry home an ember from the communal bonfire, the people would hollow out a turnip so they could walk home with the fire still burning.

The other story (which is a little more spooky) is that Jack-o-lanterns date back to the 18th century and are named after an Irish blacksmith, called Jack, who colluded with the Devil and was denied entry into Heaven.

Jack was condemned to walk the earth for eternity but asked the Devil for some light. He was given a burning coal that burnt into a turnip that he had hollowed out. Some Irish believe that hanging a lantern in their front window would keep Jack’s wandering soul away.
When the Scot-Irish emigrated to America, they adapted the tradition and used a pumpkin instead as it is more difficult to find turnips.


The community would gather around the bonfire and would be dressed up in elaborate animal skins and heads.

The idea was that the evil spirits would be scared off by the fires. Then if the spirits happened to be wandering the earth and bumped into one of the Celts they might think they were spirits themselves because of their disguises, and let them go free. This is where our tradition of dressing up comes from. 

Trick or Treat

Trick or treating originated centuries ago. In Ireland, the poor would go from door to door to rich people's homes and ask for food, kindling, or money. They would then use what they collected for their celebrations on Halloween.


(Pronounced kohl cannon)

This is the traditional dinner to have on Halloween night before you head out for an evening of fun and mischief. It is a simple dish made with boiled potatoes, curly kale (a type of cabbage), and raw onions.

Traditionally coins were wrapped in pieces of clean paper and slipped into children’s colcannon for them to find and keep. Sometimes people also hide a ring in the colcannon. Whoever finds the ring will be married within the year.


Barmbrack (from the Irish name Bairín Breac) is a traditional Irish Halloween cake which is essentially a sweet bread with fruit through it as well as some other treats.

Shop-bought barracks still contain a ring but if you make it at home and add your own treats it’s even more fun.

Each member of the family gets a slice and each prize has a different meaning:

  • The rag – your financial future is doubtful
  • The coin – you will have a prosperous year
  • The ring – impending romance or continued happiness
  • The thimble – you’ll never marry

Snap apple

There are many games that are played on Halloween night and snap apple or bobbing for apples is one of them.

In snap apple, an apple is suspended from a string and the children are blindfolded and their arms tied behind their backs. The first child to get a decent bite of the apple gets a prize. Bobbing for apples is when some apples are dropped into a basin of water and the children have to go in head first and try to get a bite.

The apples are associated with love and fertility. It is said that whoever gets the first bite will be the first to marry. It was also thought that if the girls put the apple they bit while bobbing under their pillow that night, they would dream of their future lover.

Shaving the friar

This old game was particularly popular in County Meath. A pile of ash was put down in the shape of a cone with a piece of wood sticking out of the top. Then each player takes turns trying to dig the largest amount of ash without the pile collapsing.

All the while competitors chant:

“Shave the poor Friar to make him a liar;
Cut off his beard to make him afeard;
If the Friar will fall, my poor back pays for all!"

Blindfolded cabbage picking

Blindfolded local girls would go out into the field and pull up the first cabbage they stumbled upon. If the cabbage had a lot of clay attached to the roots their future lover would have money. If the girl ate the cabbage the nature of their future husband would be revealed, bitter or sweet.

Anti-Fairy Measures

As we all know fairies and goblins collect souls as they trawl the earth on Halloween night. The story goes that if you threw dust from under your feet at the fairy they would release any souls they kept captive. However, over the years this legend was changed.

Farm animals would be anointed with holy water to keep them safe through the night. If animals showed ill health on Halloween they would be spat at to try to ward off the evil spirits.
